Practice Questions of Divergence and Curl

1. Define Divergence.

Divergence is a measure of how a vector field’s values spread out from a point. It signifies the rate of outward flux or expansion of a vector field at a specific location in space.

2. What is the Meaning of Curl?

Curl describes the rotational behavior of a vector field around a point. It indicates the tendency of the vector field to circulate or rotate about an axis at a given point.

3. What is Divergence of a Vector Field?

Divergence of a Vector Field : It measures how much the vector field is spreading out or converging at a particular point. Mathematically, it is the sum of the partial derivatives of the vector field’s components with respect to each coordinate.

4. What is Curl of a Vector Field?

Curl of a Vector Field  is rotational aspect of the vector field around a specific point. The curl is computed by taking the cross product of the del operator with the vector field.

5. How to Find Divergence of a Vector Field?

To find the divergence of a vector field , calculate the sum of its partial derivatives with respect to each coordinate,

7. Is the Divergence of Curl 0?

The divergence of the curl is always zero.

8. What is the Formula for div and curl?

The formulas for the divergence and curl of a vector field are

  • div F = ∂F1/∂x + ∂F2/∂y + ∂F3/∂z
  • curl F = (∂F3/∂y − ∂F2/∂z, ∂F1/∂z − ∂F3/∂x, ∂F2/∂x − ∂F1/∂y)


Divergence and Curl

Divergence and Curl are important concepts of Mathematics applied to vector fields. Divergence describes how a field behaves concerning or moving away from a point, while curl measures the rotational aspect of the field around a specific point. Divergence operators give scalar results whereas Curl operators give vector results.

What is Divergence?

Divergence, in vector fields, tells us about the behavior of the field concerning or moving away from a specific point. Divergence of a vector field in either two-dimensional (R2) or three-dimensional (R3) space at a given point P gauges how much the field is “outflowing” at that point. When represents the velocity of a fluid, its divergence at point P indicates the net rate of change, over time, of the fluid amount moving away from P (the tendency of the fluid to flow outward from P. Specifically, if the volume of fluid entering P equals the volume flowing out, the divergence at P is zero....

What is Curl?

In vector field analysis, the curl is our second focus, gauging the rotational aspect of the field around a specific point. Consider a fluid’s velocity represented by the vector field . The curl of at a point P is a vector indicating how particles near P tend to rotate around the axis aligned with this vector. The curl’s magnitude at P reflects the speed of rotation around this axis. Essentially, the curl signifies the vector field’s “spin” at that particular point. To visualize, think of placing a paddlewheel in the fluid at P, aligning its axis with the curl vector. The curl then characterizes the paddlewheel’s inclination to rotate....
